Method, device and system for broadcasting system information

Abstract

The embodiment of the invention discloses a method for broadcasting system information. The method for broadcasting system information comprises the steps of obtaining preset global system information which comprises pre-divided basic system information and system information related to a terminal; broadcasting the basic system information on a broadcasting channel; receiving messages uploaded by a user terminal through an uplink channel, and extracting a system information requirement message included in the messages; determining target system information in the system information related to the terminal based on indication of the system information requirement message; and sending the target system information to the user terminal. By adoption of the method for broadcasting system information, all the system information is not required to be sent to the terminal actively for one time, fewer capacity resources of a base station broadcasting channel are accordingly occupied, and the resource utilization rate of the broadcasting channel is increased.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and system for broadcasting system information. Background technique [0002] With the development of communication technology, communication protocols are becoming more and more loaded. For example, in the traditional LTE system, the system information that the base station needs to broadcast to the user terminal is very complicated, including the Master Information Block (MIB) and multiple A system information block System Information Blocks (SIBs), the optical MIB defines system information such as downlink system bandwidth, PHICH resource indication, system frame number (SFN), cyclic redundancy check CRC using mask, and information on the number of antennas , and besides MIB, SIB has defined more than 20. In traditional technology, the broadcast of system information needs to occupy the broadcast channel and the modulation and demodulation level ad...

AI Technical Summary

Problems solved by technology

In traditional technology, the broadcast of system information needs to occupy the broadcast channel and the modulation and demodulation level adopted needs to meet the requirements of covering the center and edge terminals, so it will greatly occupy the capacity resources of the broadcast channel of the base station, resulting in low resource utilization of the broadcast channel
